New conducting molecular metal/polycarbonate bilayered composites: (ET)2IBr2/PC-, (BET)2 IBr2/PC- and (BET)213/PC-films

摘要

Preparation of thin layers of oriented microcrystalsof molecular metals using chemical oxidation by either I_2, IBr orICl vaporous of the polycarbonate films containing 2 percent ofET or BET is presented. Compositions and crystal structures of theconducting layers were analyzed by X-ray, ESR and Ramanspectroscopies. The polycrystalline #beta#-(BET)_2I_3 layerreveals a metal-like R(T) dependence (d.c.) down to low temperature.
